[Interest of BNP value after cardiac resynchronisation therapy]. / Intérêt du dosage du "brain natriuretic peptide" (BNP) après resynchronisation cardiaque.

ABSTRACT

Cardiac resynchronisation therapy (CRT) induces, among responders, an early but sustained decrease of BNP levels. The changes of this parameter at 6 months, as well as its relative variations over the same time period, allow identification of the patients susceptible to benefit from CRT. Measurements of BNP levels might offer a useful tool for treatment optimisation in this particularly frail group of patients.
